BRICK-MACHINE.

SPECIFICATION `forming part of Letters Patent No. 295,558, dated March v25, 1884.

Application filed October 18, 1853.

drawings.

This invention has relation to brick-ma chines; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claim appended.

Inthe drawings hereto annexed, Figure lis a perspective View of myimproved brickma chine with the nose-piece detached, for the..

purpose of showing the construction more clearly. Fig. 2 is a side view. ,Fig 3 is a top view. Fig. 4 is a longitudinal vertical sectional view on the line x m in Fig. 3. Fig.

' 5 is a transverse vertical sectional view on the line yy in Fig. 3.

The same letters refer to the same parts in all the figures.

A in the drawings designates the base,which supports aframe, B, having bearings or boxes for thel main` driving-shaft C, which is provided at its rear end with aband-wheel, D, or

other suitable means for'receivin g motion from any desired power. The frame B is provided with a semicircular flange, E, serving to support the front end of the lower half, F, of the temperingchamber G. The latter, which is constructed, mainly, of the two halves or sections F and H, is of a tapering or conical shape, as shown. The sections Fand Hare provided with laterally-projecting fianges I J, united by screws or bolts K, and the flanges I of the lower section, F, are provided with lugs L, connected by bolts or rods M with the frame B, to which Vthe said section F and the temperingchamber are thus firmly secured. If desired, additional lugs and fastening-bolts `may be provided without departing from the spirit of my invention. The front end ofthe tempering-chamber rests upon and may be (No model.)

the inclined nose-piece or cover S, forming a tapering chamber, T, which I denominate the pressure-box. p

U is the mold-wheel, which is mounted to revolve in a horizontal plane upon the central. axis or upright, P, as shown. The said moldwheel consists of a disk of suitable proportions, the periphery of which is provided with teeth or cogs V, and the body of which is provided .with radial slots W, which form the moldboxes. The bottoms of the latter are provided with anges X to retain the plungers Y, which are provided with downwardly extending bearings Z, carrying friction rollers or casters A. The base A supports a cam-shaped or in; clined track, B', that engages the friction-rollers of the plungers, so as to force the latter in an upward direction on the upward incline of 7o the track B as the wheel revolves. The said track being located out of the line of the tempering and pressure chambers will allow the plungers to drop upon their anges while they pass under the pressure-chamber from which the molds receive their charges of clay, in order that the molds mayjreceive their charges of clay. The mold-wheel engages and is operated by a pinion, C', mounted upon a verti cal shaft, D', which is journaled in suitable boxes or bearings upon the base A and the plate N, as shown. Said shaft D also carries a bevel-wheel, Fl, engaging a pinion, F, on the front""` end of the main driving-shaft C, which has a bearing in one of the uprights O.'

Journaled in the frame B is a horizontal` shaft, G', extending longitudinally through the tempering-box, and provided with the customary grinding-knives, H. In the construction and arrangement of these no novelty is herein claimed. The rear end of the shaft G has a v per, K', through which the clay is fed into the machine.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of vthis machine will be readily understood by those skilled in the art to which it appertains. Vhen the machine is in operation, the clay is fed through the hopper into the tempering-chamber,where IOO e y '295,558 l the spirally-curved knives serve to force it l cure by Letters Patent ofthe United States- 25 into the tapering pressure-box. rIhe inclined cover of the latter serves to force the clay, with a considerable degree of pressure, in a downward direction into the dies of the moldwheel, as they pass in succession under the said pressure-box. As the mold-wheel continues its revolution, -Jthe plungers are forced upwardly by the inclined track or cam above described, thus expelling the brick, which may then be readily removed. A

This machine possesses in asuperior degree the advantages of simplicity and ease of operation, and great power is exercised in compressing the clay in the molds or dies. This is due to the relative arrangement of the temperingchamber, pressurebox, and the moldwheel.

The general construction and arrangement of parts are simple and elicient, and the machine may be constructed at a less cost than ditferently-constructed machines of like capacity.

I claim as my invention and desire to se- In a brick-machine, the combination, with the tapering conical horizontal temperingchamber G, provided with the nosepiece S, and rotary knives for feeding the clay to the discharge, of the mold-wheel arranged horizontally beneath the discharge-opening, provided with molds having bottom anges to support the plnngers, the plungers provided with downwardly-projecting bearings carrying friction-rollers, and a cam-track out of line with'the discharge-opening, on which the friction-rollers travel to operate the plungers to expel the brick, and upon which they descend to permit the molds to be filled at the proper time, and mechanism for operating theI 4o parts, substantiallyv as specified.

In testimony thatv I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
